An ultrasonic generating device, which can generate an ultrasonic with complex waveforms, includes a first waveform generating element, which emits a first waveform, and a second waveform generating element. The second waveform generating element periodically adjusts the first waveform with at least one frequency higher than the first waveform to form a second waveform in the first waveform. The two waveforms are superposed to form the complex waveform. By means of the tunneling ability of the first waveform, the second waveform can be carried into the target region with the complex waveform, therefore have a biological medical effect.一超音波產生裝置,用以產生一複合波形超音波,包括一第一波形產生元件,發出第一波形;以及一第二波形產生元件,此第二波形產生元件用至少一高於第一波形的頻率,週期性調節第一波形,以在第一波形中形成一第二波形,並與第一波形疊加成複合波形超音波。藉由第一波形之穿隧能力,此複合波形超音波能將第二波形帶入特定目標物內。以達具有生物效應之醫療效果。100‧‧‧複合波形超音波102‧‧‧第一波形104‧‧‧第二波形
